Variables Used
Intensity of Pressure of Wave - (Measured in Pascal) - The Intensity of Pressure of Wave is defined as the pressure intensity of the wave produced at the gradual closing of valve.
Density of Fluid in Pipe - (Measured in Kilogram per Cubic Meter) - Density of fluid in pipe material shows the mass of the liquid in a specific given volume. This is taken as mass per unit volume.
Length of Pipe - (Measured in Meter) - Length of Pipe describes the length of the pipe in which the liquid is flowing.
Flow Velocity through Pipe - (Measured in Meter per Second) - Flow Velocity through Pipe is the velocity of the flow of any fluid from the pipe.
Time Required to Close Valve - (Measured in Second) - Time required to close valve is the amount of time required for closing the valve.
